whom iteracy concern:

Be it known that 1, (names I]. WILLIAMS, Jr., a citizen of the United States, residing at Chicago, (.ook county, Illinois, have invented a certain new and useful Im )rove'ment in 'lrussed Beams, of which the i fall, clear, and exact description, such as will enable others skilled in the art to which it apertains to make and use the same, reference )eing had to the accompanying drawings, forming part of this specification, in which-- Figure 1 is a plan view, partly in section, of one end of my improved )rake beam; Fig. 2 is a sectional view on the line 2-2 of Fig. 1 Fig. 3 is a detail view oi the thrust block;

To all Fig. 4 is a plan view, partly in section, of a improvement in trussed beams,

modified form of beam; Fig. 5 isa cross sectional view on the line 5-5 of Fig. 4; Fig. (i is a plan view, partly in section, of another modified form of beam; Fig. 7 is a sectional view on the line 7-7 of Fig. 6; Fig. 8 is a lan view, partly in section, of another modified form of beam; and Fig. 9 is a sectional View on the line 99 of Fig. 8.

This invention relates to a new and useful the object being to provide the end of the beam with a com )I(-SS1()I1 member in the form of a yoke WlIlC- h takes up the end thrust of the compression member and also the pull of the tension member.

Another object is to provide an interlock between the tension. member and thrust yoke, so that when the parts are assembled they may be held in positionby a single rivet, thus enabling the truss of the beam to be preserved and the brake head, if the trussed beam is used as a brake beam, to be renewed.

In the drawings, in Figs. 1, 2 and 3, 1 indicates the compression member in the form of a rectangular bar, and 2 is the tension memher in the form of a flat plate. I have not shown the strut of the brake*beam, but it is obvious that any wellknown strut ,may be employed in connection with my improved beam. The end'of the compression member 1 is preferably beveled olf as at 1, Fig. 1, while the end of the tension member 2 is rovidcd with an enlargement 2 formed by olding the tension member upon itself, upsetting the ends of thetension member, or welding a piece on the end of the tension member, as best suited to the tastes of the manufacturer. 'lhis enlargement is preferably formed ollowing is a desired.

a recess 3" in which 1s received the tongue 2 on the front'face of the tension member, and to form a secure interlock the enlargement is extended .forwardl to form a tongue 2".

3 indicates a yoke constituting the thrust member, which yoke is in the form of a strap and is provided on its forward edge with an enlar ement 3 either by folding the front leg of the yoke upon itself, upsetting the end of the front leg, or welding a piece thereto, as This enlargcmentis provided with of the tension member.

arts the tongue on the fitted in the recess in the forward leg of the yoke, and the end of the compression mem- In assembling the er l is slipped laterltlly in position, after which a securing device rivet the rear leg of the oke to the compression member. When tie parts are thus assembled and secured together it is obvious that the brake head whose'socket 5 is shown in Figf l, may be inserted in osition or removed from osition without estroyin r the integrity of t 1e truss. When the brake lead is in position I refer to employ some securing means, as or instance'the rivet 6, for holdin the brake head in place. Of course, the yolie 3 hu s the beveled end of the compression mem er, and by so doing exerts a clam ing action on the yoke tending to force the orward leg thereon into close contact with the enlarged end of the tension member.

In Figs. 4 and 5 I have illustrated a construction similar to that shown in Fig. 1, except that the end of the compression member is not beveled and the tension member is not provided witha tongue 2'.

In Fig. 6 I have shown the compression member in'the form of a channel 7 in which the enlarged ends of the tension member 8 and the yoke 9 are received, said enlarged ends practically filling the space between the flanges and ma ing a solid foundation for the socket of the brake head 10..

In Figs. 8 and 9 I have shown the compression member in the form of an I-beam 11, the tension member 12 and the yoke 13 being constructed substantially the same as in Fig. 6. Where an I-beam is used the socket of the brake head 14 must of course conform to the rear flanges on the I-beam, as shown in Fi 9. r

In igs. 6 to 9 inclusive means, in the form of rivets, is shown for securing the brake heads in position. When this means is re- 4 is employed to tension member is position.

v 55 ing an interlockin moved the brake heads can be removed, but.

the integrity of the truss will be reserved without anys ecial securing means yreason of the fact t at the flanges of the channel or I-beam, as the case ma be, tend to hold the tension member and tli In assembling the parts the enarged end of the tension member is arranged in the channel of the compression member, after which the enlarged end of the thrust yoke is arranged in position and the rear leg of the thrust yoke is bent behind the leg of the .compression member. When the brake head is arranged in position 'it will be seen that the back wall of the socket thereof holds the rear leg of the thrust yoke in position and prevents any movement thereof. 1 While I have illustrated in the accompanying drawings a brake head as the art oooperating with my improved truss earn, it

is obvious that my invention is e ually applicable to bolsters, that is, body olsters and truck bolsters, and in the latter event the brake head will be replaced-by an end casting ,forming the spring seat member ofthe bolster.

I am aware that minor changes in the construction, arrangement and "combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departingfrom thenature and rinciple of my inventlon.

Having thus escribed the invention, what. is claimed as new-and desired to be secured by Letters Patent is: r

1. In a trussed beam, a compression member, a tension member arranged with its end against the compression member, and a A thrust member embracing said compression and tension members and provided with a shoulder that cooperates with a shoulder on the tension member; substantially as described.

2. In a trussed beam, the combination with a compression member, a tension merry ber whose end engages the end of the compression member, said tension member havin an enlargement at its end, and a thrust yo e engagin the compression member and aving an e argement for cooperating with the enlar ement of the tenslon member; substantia y as described.

' 3. In a trussed beam, the combination of a compression member, a tension member havenlargement provided with a tongue, an a yoke secured to the com ression memberand provided with an inter ocking enlargement in which a recess is formed for cooperatingwith the interlocking rust yoke in enlargement and tongue of the tensionmember; substantially asrdescribed.

4. In a trussed beam, the combination of a compression member, a tension member havmg an enlarged end, a yoke having an enlartged end for cooperating with the enlarged en of the tension member, said yoke extend ing around the end of the compression member and alon the ,rear. face thereof; substantially as escribed.
